MGEHR/MGEHL for MGMN Grooving Tool Holder MGEHR1212 MGEHR1616 MGEHR2020 MGEHR2525 MGEHR3232 External slotting Turning

The MGEHR/L series extended-length external grooving tools redefine precision in deep or hard-to-reach grooving tasks, leveraging the trusted performance of the MGEHR platform. Crafted with high-strength alloy steel shanks and ultra-fine grain carbide inserts, these tools combine extended reach with uncompromised rigidity, eliminating vibration even in high-speed machining of deep grooves (up to 25mm depth).

Optimized for MGEHR/L’s signature chip breaker geometry, they ensure efficient chip evacuation across materials like stainless steel and alloy steel, avoiding workpiece scratches. The precision-ground cutting edges maintain ±0.01mm dimensional tolerance, while the extended design adapts to large workpieces or deep cavities. Backed by strict MGEHR/L quality control and field validation, they are reliable for automotive, mold, and heavy machinery manufacturing.

Product Details

The MGEHR/L series extended-length external grooving tools, paired with high-performance Grooving Tool Holder, are engineered for deep, hard-to-reach grooving tasks in precision CNC machining. The tool body integrates an extended alloy steel shank (length options: 100mm-200mm) and ultra-fine grain carbide inserts (WC-Co content ≥94%), while the matching Grooving Tool Holder features a rigid clamping structure with precision locating pins, ensuring concentricity tolerance ≤0.008mm between tool and holder.

The Grooving Tool Holder is compatible with all MGEHR/L extended-length tool variants (1212, 1616, 2020, 2525, 3232 shank sizes), adopting a quick-change design for efficient insert replacement. The tool’s cutting edge undergoes 3-stage precision grinding: coarse shaping, fine grinding to Ra≤0.2μm, and edge honing (0.01-0.03mm radius), reducing cutting force by 18% and preventing chipping.

Optimized for the Grooving Tool Holder’s stability, the tool handles grooves 1-12mm wide and up to 30mm deep in materials up to HRC 48 (e.g., duplex stainless steel, alloy steel). Each set undergoes CMM dimensional inspection and 72-hour continuous cutting tests. Backed by the Grooving Tool Holder’s vibration-damping design and MGEHR’s 12-month warranty, it’s ideal for automotive axle deep grooving and mold cavity machining.
